Specification of Letters Patent. Application filed December 31, 1909, Serial No. 535,860. Renewed Kay 29, 1911.

To all iblwm it may concern:

Be it known that I, Oscar: L. Bowers, a citizen of the United States, residing at Willard, in the county of Alexander and State of Illinois, have invented a new and useful Wire-Tying Device, of which the following is a specification.

This invention has reference to improvements in wire tying devices and it is designed more particularly for tying balc wires in bale presses.

In accordance with the resent invention each tie for the bale is ma e up of two wire strands united at the ends and then encircling the bale and finally fixed together at the other ends to com late the tie.

The invention will e best understood from a consideration of the following de- .tail description taken in connection with the accompanying drawings forming a part of this specification, in which drawings,

F i re 1 is a side elevation of a portion of a ali ng press taken from the wire tying sideshown' in Fig. 1 and'also illustrating coaeting arts. Fig. 3 is an elevation ofthe wire tying structure shown in Fig. 1 looking toward the power end of the press, the baling chamber being shown in section. Fig. 4 is a view of a portion of the structure of Fig. 3 looking toward the discharge end of the press, some parts being shown 1n section. Fig. is an enlarged view of the' wire t 'ing structure of Fi 1, the view being ta on at a slightly di erent angle than the showing of Fig. 1. Fig. 6 is a detail yiew showing wire clamps in plan. Fig. 7

' IS a detail view of the means for severing the wire after being twisted. Figs. 8 and 9 are detail views of a portion of the twisting mechanism and a support therefor. Fig. 10 is an elevation of a part of the structure on the side of the machine remote from that shown in Fi 1. Figs. 11, 12 and 13 are structural diagrams Illustrating different phases in the operation of the device.

Referring to the drawings there is shown a balin press in so far as is necessary for the un erstanding of the present invention, the baling chamber 1 and usual ho )per 2 being the only'parts illustrated, it eing understood of course that the usual pluliger is present and that suitable operating means for the plunger'are also considered as being present.

cent to the baling chamber is a frame 3 of suitable shape to support the several structures making up the twisting mechamsm.

I In the particular structure illustrated each bale is to, be secured b strands spaced a and each encirc ing strand is made up of two members joined together at the ends in a manner which will hereinafter appear. There are therefore provided two twisting mechanisms which-are identical in all respects and hence in the following description reference will be had to one of these twisting mechanisms only with the understanding that the description applies equally well to the other twisting mechanism.

Considering one twisting mechanism, there is secured to the frame 3 a stub-shaft 4 upon which is mounteda gear wheel 5 having on one face a bevel pinion 6 and on the other face a cam 7, the cam member 8 of which latter has but a short active length as compared with the circumferenceof the cam body 7, said member 8 being in the nature of a projecting tooth. On the face of the gear wheel 5 carrying the bevel pinion 6 there is formed a cam member 9in the form of a ledge which is for the greater por tion of its length concentric with the axis of rotation of the gear wheel 5, this concentric portion constituting the larger diameter of the cam, and for the remainder of the cam surface it approaches the said axis of rotation of the gear wheel 5. The gear wheel 5 is driven by a bevel pinion 10 engaging the bevel pinion 6, and the pinion 10 is mounted on a shaft 11 journaled in the frame 3 and below the same carrying another bevel pinion 12 meshing with a bevel pinion 13 on one end of a shaft 14 extending below and to the other side of the baling chamber 1.

The gear wheel 5 is of the mutilated type havin a continuous series of gear teeth 15 exten ing about the eater portion of its circumference and a ort series 16 of gear teeth spaced at each end from the main series 15 of gear teeth and to one side of the space as aratin the two series of gear edges 17 ore purpose which will presently appear. mesh with a pinion 18 provided with a hub 19 mounted in bearin formed-at the ends of brackets 20- which are formed with The gear wheel 5 is in legs 80 that amass to pigiona.

two wire art and enclrc ing the bale legs of the b pinion 18 is formed with diametrically disposed recesses 21 extendin from the periphery-of the pinion into is e hub 19, this pmio'n 18 being esigned as a twisting ceases strands which, when the pinion is rotated, become twisted together. On one face the inion 18 is provided with anenlargement22 wsich is flattened at diametricall opposite points as indicated at 28, the sai flattened portions 23 being enga ed by the ledges 17 so that under these circumstances the pinion 18 is held from rotation, but the pinion will be rotated b the engagement of either series of teet 15 or 16 therewith when reached by such series of teeth in the rotation of the ar wheel 5.

Formed in the side walls of the baling chamber at a point coincident with the hopper 2 and opposite each gear wheel 5 is a slot 24 longitudinal of the press. At each end of the slot there is secured a bracket 25 with diver nt legs so that the bracket straddles e slot. Carried by the two brackets 25 at the ends of a slot 24 are legs 26 of a frame 27, these legs being esivotal connected to the brackets. Mount in eac bracket on one of the legs thereof, this being the lower leg]: in the particular instance shown is a ed clampmember 28 while formed on eachleg 26 of the frame 27 is a co-acting clamp member 29.

Pivotally secured to the frame 3 80 the free end of which is inoperative relation to the cam 9 formed on the gear wheelfi. This free end of the arm 30 is connected by a link 31 to the frame '27 A sprin 32 connects the frame 27 where joine by the link 31 to a projection '33 cm the arm 30. The spring 82 is of the contractile type and tends theref re to draw the frame 27 toward the projecting member '33, thus also tending to move the free end of the arm 30 toward the cam Band to sgparate the clamp members 28 and 29. hen the-free end of the arm30 is resting on the portion of the cam 9 of small diam eter then the clamp jaw 29 is separated from theiclamp jaw 28 but when the portion of the cam 9 of lar er diameter is brought into engagement wit the free end of the arm 30 the latter is rocked on its pivot support and causes a rocking of the frame 27 on the pivot sup ort of the latter in the bracket 25 in a irection to bringmthe cammmber 29 r 28 at the same time pinion and the re is an arm toward the cam mem extendingthe spring 32.

Mounted on the frame 3 in pivotal re lation thereto and located along the face of the gear wheel 5 carryin the cam member 7 is an arm 34 provide with a tooth or projection 35 in co-active relation to the tooth or cam projection 8 on the cam 7 21 being designed to receive wire The other edge of the arm 34 remote from that carryin the cam projection or tooth 85 is forms into-a knife edge, this edge being indicated at 36. The location of t 0 arm 34 is such that the knife ed e 36 me be brought into engagement wit the hu 19 at one side of the gear pinion 18, being forced into firm engagement therewith b the action of th cam tooth 8 upon the toot or projection 35. A spring 37 tends to hold the'arm 34 with the pro ection 35 in the path of the tooth 8 of the'cam 7.

Mounted on a suitable bracket fast to the frame or an port-3 and adjacent to each r wheel is a post or stem 38 for a spool 39 carryin a supply of wire 40. The spool may be he a spring 41 applied to wit an desired degree of friction by an ad'ustab e nut 42.

the side of the baling chamber remote from that ca ing sustained there y, is a shaft 48 journaled in suitable brackets 44 and carrying two angle arms 45, these arms co-acting with the two twisting mechanisms on the opposite side of the baling chamber.. one of the arms 45 will apply to both, and the following description is to be so under The arm 45 is provided with an angle extension 46 which may be about at right an les with the main rtion of the arm 45 an at the free end e a le extension 46 is formed into two fingers 4 --48, the finger 48 diverging from the finger 47 so that the ends are separated. At the free end of the finger 47 are rollers 49'and at the, free end of the fin 48 is a roller 50, while at the angle 0 junction between the main portion of the arm 45 and its extension 46 is another roller 51.

Mounted on the frame 1 of the balin chamber is a reel 52 carrying a wire stran 53. The shaft '43 is under the control of an arm 54 b means of which the shaft 43 1318-; be rock suflicientl& to carry, the fingers 4 completely across through the bones other side of the be mg chamber, the normal position of the fingers 47 and 48 being exthe baling chamber on the side terror to thereof where the arms 45, are located, it being understood that suitable passages or slots are rovided in the corresponding side of the b ing chamber for the introduction of the fingers 47 and 48.

The mechanism for causing the rocking movement of the shaft 43 need not be described in detail in this case sincemechanism such as shown in LettersPatent No. 942,305 granted to me on December 7, 1909 for automatic wire tying machine may be utilized for this purpose.

The strand 40 is carried from its reel or A description of the frame 3 and parts e baling chamber and nding slot 24: in the s 001 39 to the adjacent brackets 25, thence t rough the slot 24 into the balin chamber Where it is united to the end .of t e strand ()3 coming from the reel or spool 52 from which latter the strand 53 is carried along the arm 45, over the roller 51, thence along the arm 46 and finger 47 and over the roller 49, there being referably two rollers 49 over one of wind? the strand is carried and around the other of which the strand is also carried before being directed into the balin chamber.

plunger be operated as is customary then the charge of material is forced along the balin chamber carrying the united strands 40 and 53 with it, the operations of introducing the material to be compressed and the reciprocation of the plunger bein re eated as often as necessary to make t e esired size of bale. The parts are so timed in operation that the requisite number of feedings and com ressions having been accomplished the shit t 43 is turned in a direction to movethe arms 45 toward the baling chamber. In the meantime the united wire strands 40 and have been forced along by the bale and suflicient wire for the purpose has been withdrawn from the reels or spools 39 and 52. The withdrawing of the strands-40 from the reel 39 has caused it to move throu h the brackets 20 into a slot or recess 21 in the a pinion 18, this slot being then in line with the space between the legs of the brackets 20 while the strand 53 has been moved from engagement with the outer one of the rollers 49 and into en agement with the roller 50 on'the end oft 1e finger 48. On the actuation of the shaft 43 the arm 45 carries thfi fingers 47 and 48 across the baling chambe on the plunger end thereof, and the strand is carried ultimate] through the slot '24 and into the space )etween the legs of the brackets 25 and 20 and into a recess 21 in the pinion 18. In the meantime-however the shaft 14 has been rotated sufiiciently to cause the gear wheel 5 to move about its supporting shaft to bring the short series 16 of gear teeth into engagement with the pi lion. 18 and cause the latter to move through one-half a revolution so that, the recess reccivin the strand 40 has moved out of the path 0 the oncoming strand 53 and the other recess has been resented for the reception of this strand. he continued rotation of the gear wheel 5 causes the teeth 16 to leave the pinion 18 while the adjacent ledge 17 is brought into enga ement with the flattened portion of the en argement 22 on one face of the pinion 18 thus holdin the latter against rotation while the stran is bcin seated in the corresponding re- 21, this locking of-the pinion preventing over-ridingof the proper osition of the parts. As soon as the stran 53 has become If now material be introduce into the press, in the usual manner and the;

seated in the recess 21 then the continued rotation of .thegear wheel 5 brings the gear teeth 15 into engagementwith the inion and causes the latter to rotate a num r of times about its axis, thus im artin a twist to the wires so that the a jacent y lying strands 40 and 53 are twisted to other on each side of the pinion 18. Just efore the .gear teeth 15 leave, the pinion 18 the cam that the strand 40 is then lying along one side of the bale and across the end thereof remotefrom the plan r where t is joined to the strand 53 whic continues across the same end of the bale and along the side thereof remote from the strand 40 and is then carried across the plunger end of the bale by the finger 48, the wire strand paying out from the reel or spool 52, being. then d1- irection toward the twisting mechanism, 55

rected along the arm 45, around the roller 5g, thence along the arm 46 and finger 47 t ence arbund one of the rollers 49 an across the space between'the fin r 47-and finger 48, thence around the rolle 60'to the point of 'unction with the stran' 40 at the other ,en 'of the bale. The portion of the strand 53 which is twisted into enga ment with the strand 40, lies between t e two fingers 47 and 48, these fingers straddling the twistin pinion 18, while the twisting is taking p etc. Just prior to the twisting action, the arm 30 is engaged by. the portion of theicam 9 of greater diameter, so that the clamp members 29 are brought toward the clam members 28 thus gras ing the wire stran s lying between these 0 amp members so that the wire strands are tightly clamped while being twisted. As soon as the twisting operation-is completed and the strands are severed along one face of the twisting pinimLlS, the rotative movement of the twisting. pinion 18 ceases since the gear teeth 16 move. out of engagement with the said pinion and the latter is held against further movement by the engagement th with of the'adjaccnt ledge 17. The parts are so timed that as soon as the wire strands are severed the cam tooth 8 rides from under the projections 35 and the spring 37 returns the knife arm 34 to its. normal position, the arm 45 is moved in a direction to ward its initial fposition, thus drawing the junction point 0 the strands 53 and 40 toa .position about intermediate of the width of the baling chamber and theparts are all shaman meal U in position for the formation of another halo, and the securing of the same by the wire strands in the manner already described.

It will be seen that two distinct wire strands are employed on opposite sides of the press for each loop about the bale, and it is evident that as many loops as may be desired may be used by simply duplicatin the mechanism. It 'will alsobe, observed that each time a tie is completed the two strands coming from opposite sides of the machine are united to form the next succeeding 100 designed to encircle the bale. It is desrable that all loose portions of the material being baled on t e plun er end of the ale should be smoothed down efore the w re strands are moved across the 'd end of the bale. For this purpose there g provided a blade55 movable into and outof the baling chamber on the plunger side of the completed bale, and this bla e is hun on the arms 56 fast on a rock shaft 57 whic V tin-if is moved by an arm 58 connected by a It 59 .to a rock'arm timwhich in turn may 1 connected .to the. opelating mechanism of the baling press by another link 70, the structure being such that the blade 55 will be withdrawn from the path of the oncoming material being compressed at-the proper time and wil also! be withdrawn fromthe path of the strands 53 when moved acrossthe plunger amid the bale.

What is claimed is 1.'-In a baling -mechanism, wire storing means on each side of the baling chamber, car a means for the wire on one side of the chamber for transporting it to oeosz oo the other side thereof, twisting means at one side of.t e'bal-ing chamber for uniting thewire from both storing means to ther, a claim tor engaging thwires on eac side of thewisting mechanism, and a cutter acting on the twisted wires between the clamps.

In a baling mechani'sm,wire storing meanson each s1d'e of the baling chamber means for directing ,a loop of the united wires about a bale, means or bringin the wires into juxtaposition, means for c amping the wires at spaced points along the-juxtaposed portion, twisti means for uniting the adjacent portions 0 the wires after encircling the ale, and severing means for cutting thetwisted portions of the wires at an intermediate part of the twist.

3. In a baling mechanism, a twisting mechanism comprising a' mutilated gear wheel with peripheral locking ledges, cams on opposite sides of said gear wheel, a pin ion in mesh with said or wheel and provided with diametric sets and a flattened projection on one face cIam members in "(operative relation to the s otted pinion,
